*) In the operating modes with 3-wire configuration or with differ-
ential inputs, two adjacent analog inputs belong together (e.g. the
channels 0 and 1). In these cases, both channels are configured
in the desired operating mode. The lower address must be the
even address (channel 0). The next higher address must be the
odd address (channel 1). The converted analog value is available
at the higher address (channel 1).
